There are boards for pre-order in the DIY Audio store for the amp. With a build guide to come. The thread about this is the one about Aleph J for the universal mounting system they are using at the DIY Audio Store.

The boards have gotten to the warehouse, and my JFets are on the way from Hong Kong (thanks Spencer). Hopefully those are the hard parts, I will be collecting the rest of it slower, as my Aleph J build is after a couple of other projects.
